Arrays are disjoint or not
Detailed guide and Python implementation for the 'Arrays are disjoint or not' problem.
Problem Statement
Write a function are_disjoint(arr1, arr2) that takes two lists of integers and returns True if they have no elements in common (disjoint), and False otherwise.
- •0 <= len(arr1), len(arr2) <= 10^5
- •-10^6 <= arr1[i], arr2[i] <= 10^6
Examples
arr1 = [1, 2, 3], arr2 = [4, 5, 6]
True
No element appears in both arrays.
arr1 = [1, 2, 3], arr2 = [3, 4, 5]
False
3 is present in both arrays.
arr1 = [], arr2 = [1, 2, 3]
True
An empty array is disjoint with any array.

Edge Cases to Watch
- Empty input structures
